Description
Stabilized zirconia (ZrO${}_2$) added hydroxyapatites were synthesized from waste eggshells at different percent weigh from 1 to 15 with an increment 2 percent weight by precipitation method. The samples were dried at 100 ${}^{\circ}$C for 48 h, grounded with pestle and mortar into powder and heated from 200 to 1300 ${}^{\circ}$C. Structure properties of samples before and after heated were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM). The XRD results show that the samples composed hydroxyapatite and tetragonal zirconium dioxide (t-ZrO${}_2$) phase. Hydroxyapatite phase was transformed to tricalcium phosphate (TCP) phase after heated at 700 ${}^{\circ}$C. At 1300 ${}^{\circ}$C, the sample had 3 phase of TCP, t-ZrO${}_2$ and CaZrO${}_3$ phase. The composited of samples were confirmed by FTIR results. The morphology and dispersive particle of samples were investigated by SEM.
